Just because something's gross doesn't mean it isn't valuable. Case in point: Whale vomit. A man taking his dog for a walk on the beach came across a pile of (maybe! hopefully!) whale regurgitation. Now he could stand to make more than $50,000 from the find.

Who would pay tens of thousands of dollars for whale excrement? The perfume industry, of course. The substance, while foul smelling when it first hits land, becomes much more pleasant as it dries in the sun—and can be used to help prolong the scent of perfume.

According to the BBC, Ken Wilman's dog began sniffing the substance (known as ambergris) while walking on Morecambe beach in England. Wilman went to investigate, picked up the stone-like object, gave it a whiff and then dropped it like a bad habit. Wilman told the BBC: "When I picked it up and smelled it, I put it back down again and I thought 'urgh.'"

Wilman left the beach, but something about his stinky discovery stayed in his mind. He did a little research at home and figured out that it was likely ambergris. He then went back to the beach and retrieved the seven-pound object. A French dealer has already offered more than $50,000.
